kindly help me to get data from the uno to my lap working on ubuntu 12.04. i am creating a program interfacing a camera in c++. i want to include a segment ie to get data from uno and use it manipulate the configurations of camera.kindly help...

and this happens in split of a second and stops.i actually wanted an output similar to that of serial monitor..ie whenever the led blinks and shows out:"led" and else it does not....so what should i do??

I'm sorry, but I don't know. :~I wanted to test the communication, but somehow I am not receiving anything with my c++ program.I have not made a c++ program on the PC for the serial port before.Normal programs like gtkterm can communicate without problem.
